    Yup, MA is right - the percentages or ppm of the components of your gas, including any CO that might be there, stay the same regardless of pressure. But at 2 ATA, there are twice as many molecules of each in a breath as at 1 ATA. So: more molecules of CO to attach to your Hgb and not let go. Then when you ascend, the ppO2, ppN2, ppHe, and ppCO all drop, but the CO molecules that grabbed onto your Hgb at depth don't let go, so your COHgb level remains high as your PPO2 drops.

    One small correction.

    Nope. The pO2 inside the tank is a whole lot higher. Just like everywhere else, the partial pressure equals the fraction times the total pressure. Air in a full aluminum 80 at 3000 psi (approx 200 bar or 201 ATA) has a pO2 of 42.21. Until you take a breath. If you could crawl inside the tank it would be like breathing air at 2000 meters depth.

    The point is nothing changes in that tank until you open it and breath it. The all the components of that gas which you are breathing are subject to the same laws of physics. Doesn't matter whether your measuring it in Bar, PSI, Or PPM. Quite Franky what ever the PPO insid

    Your math is flawed. I say this because you can not know the Psi, Bar, Ata, Ppm, Particial Pressures, identities of any of the gas or if the cat living inside is alive or dead until you open the tank and analyze the contents. When you come down to it that's the real point.

    Hmmmmm.... As an artist, I thought you would have a better handle on the abstract.....

    I would have thought you would know better then assume. Just saying there's a difference between math and guessing.

    Said the artist to the math professor. Would you really like to compare algorithms? I'm sure mine is bigger........

    Does Schrödinger know that you have his cat?

    And you thought building a ship in a bottle was hard.
